WebThe invention relates to automation and switching technology and can be used in automatic control systems, control and communication as a switching element with memory, controlled by short-term different-polarized pulses. The aim of the invention is to simplify the device and reduce the tripping time. When a positive voltage pulse is applied to the input, coils 4 … WebFerreed relay? the name ferreed denotes a reed relay in which the dry reed switch is combined with one or more magnetic members; the magnetization can be changed by …

Reed switches have been manufactured since the 1930s. Compared with armature-based relays, reed relays can switch much faster, as the moving parts are small and lightweight, although switch bounce is still present. [1] Also, they require less operating power and have lower contact capacitance. See more A reed relay is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move … See more A few million reed relays were used from the 1930s to the 1960s for memory functions in Bell System electromechanical telephone exchanges. … See more Reed arrays passed out of use in the mid-1990s, being unnecessary in digital telephone systems such as DMS-100 and 5ESS switch. Reed relays have continued in their uses outside the telephone industry, such as for automatic test equipment See more • Hovgaard, Ole M.; Perreault, George E. (1955-03-02).
